Thanks for your help. I switched to glib 2.42.0 and do not see
significant CPU improvement so far.<br>
<br>
I remade some perf stat measures (<b><a moz-do-not-send="true"
href="http://fpaste.org/145793/50742514/">http://fpaste.org/145793/50742514/</a></b>)<br>
You can see that the whole pipeline context switch is 0.005
M/sec. udpsrc (RTP packets reader) take 0.004 M/sec.<br>
<br>
Using perf top again I do not see any particular function
consuming CPU ( see <b><a moz-do-not-send="true"
href="http://fpaste.org/145795/45076731/">http://fpaste.org/145795/45076731/</a></b>)
Do you agree with that ?<br>
Adding a small sleep allow me to save 4-5% on udpsrc (see patch
in attachment).

</div>
<div>I checked the resulting mkv file. No frames are dropped
using the workaround. I would like to avoid the use of sleep
but it looks like I do not have other simpler solution for the
moment.</div>

</div>
<div>Please feel free to advice me.</div>
<div>Cheers,</div>
